Saturday: Pennyfest at Empire. Does a single-day event really count as a fest? It might be stretching the definition, but we’ll let it slide for this one with its solid offerings of top-notch regional indie rock. Gigs by San Antonio outfit Girl in a Coma have been rare over the last couple years as lead singer Nina Diaz focused on her solo career, but they kick off a national tour later this fall, and they’ll be in Austin to headline this shindig. Also on the bill, presented by Penny Loafer PR and 101X Homegrown Live, are Emily Wolfe, Ghost Wolves, Darkbird and many more. $12-$17. 6:30 p.m. doors. 606 E. 7th St. empireatx.com. — D.S.S.

Saturday: Donald Fagen & the Nightflyers at ACL Live. It’s not Steely Dan, granted, but co-leader Fagen will be playing many of that band’s biggest hits on this tour, as well as choice cuts from his handful of solo records. Backing him is a band of younger musicians he’s recruited from the area around his Woodstock, N.Y., home: guitarist Connor Kennedy, keyboardist Will Bryant, bassist Brandon Morrison and drummer Lee Falco. $69.50-$99.50. 8 p.m. 310 Willie Nelson Blvd. acl-live.com. — P.B.
